Cryptosporidium & Giardia
Cryptosporidium and Giardia
The AWQC provides a NATA accredited analysis catering for the detection and enumeration of Cryptosporidium and Giardia.
Cryptosporidium and Giardia are transmitted by the faecal oral route, and cause gastrointestinal illness. They have been detected in all types of source waters, drinking water, swimming pools, sewage and sewage effluents. Their occurrence in surface waters can be dependent on large rainfall events and contamination by sewage effluents.
Cryptosporidium was best known as a parasite of pasture animals but is now regarded as an important human pathogen.
Cryptosporidium has a thick walled oocyst, which are shed in faeces and survive outside the body for long periods of time and are very resistant to chlorine disinfection.
Giardia has been known as a human parasite for 200 years, but has been regarded as an important agent of disease only since the 1960s. The active stage of Giardia is a trophozoite which attaches to the intestinal wall by an adhesive disc. The infectious stage (a cyst) is shed in faeces in large numbers and is the only stage of the life cycle that can survive in the environment.
